hey everyone
i took my boat out it has a johnson 1999 90hp (model # J90PLEEB) this weekend. it has a bad miss in it. last summer i unhooked the vro. it would idle rough. but now it has a real bad miss in it. should i hook my vro back up or does anyone have any ideas what it could be. i took the plus out and thet are brown and dry with no oil build up on them. i mix my oil at 50 to 1 thanks
